open street maps (osmdroid) shows grey tiles not map in PC

I am using osmdroid to get open Street maps in my app. I had build my project with the needed jars (osmdroid) and added all needed permissions in the manifest. But when I try to debug my app in android emulator (adt eclipse) I am not able to see the map, only grey tiles. My project is working fine because if I debug in a smartphone I am able to see the map, the problem is only with the emulator. I have done some research but I only found information of google maps solutions but not open street maps (osmdroid). Does somebody know how to solve this issue? this is how I show the map in xml file ``` <org.osmdroid.views.MapView android:id="@+id/mapView" android:layout_width="fill_parent" android:layout_height="322dp" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" > </org.osmdroid.views.MapView> ``` this is my main activity ``` mapView = (MapView) findViewById(R.id.mapView); mapView.setTileSource(TileSourceFactory.MAPQUESTOSM); mapView.setBuiltInZoomControls(true); mapView.setMultiTouchControls(true); mapView.setUseDataConnection(true); ``` These are my permissions in manifest: ``` <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.INTERNET" > ``` and the jars added to my build path ``` osmdroid-android-4.2.jar osmdroid-thrid-party-4-2.jar slf4j-1.7.7.jar ```
